Horizontal alignment highway
WebHorizontal alignment of a highway defines its location and orientation in plan view. Vertical alignment of a highway deals with its shape in profile. Distance along a horizontal alignment is measured in terms of stations. A full station is defined as 100 ft (30.48 m) and a half station as 50 ft (15.24 m). WebTo avoid the appearance of inconsistent distortion, the horizontal alignment should be coordinated carefully with the profile design as presented in Section 2.3. Such coordination is especially important at railroad-highway grade crossings. For additional information concerning general and design considerations for horizontal alignment and ...
